Fig. 3 ing the right and left side elements of the radiator is a, perspective View of a pair of side elements shell simultaneously from a single blank by one die pressing operation, not only is great saving This invention relates to automobile radiator shells, and more particularly to a composite shell assembled from a plurality of initially separate parts, therebyV enabling distinctive, ornamental of the shell disposed in their ultimate relation to each other before being interconnected by an in-V termediate ornamental panel or coupling section. Fig. 4 is a perspective view illustrating one method of producing the side elements of effected in the material required and the waste thereof reduced to minimum, but the draw or stretch of the material is equalized during the forming operation, and the draw of each section is opposed to that of the opposite section, which has been found to be quite advantageous. After conjoint formation of the right and left side elements I they are longitudinally severed one from the other and trimmed toremove as waste material the blank holding areas by which the sheet is gripped during the forming operation. While the separate si'de elements thus produced may be directly interconnected one to the other by welding or otherwise, providing they are sufiicient size, they are preferably interconnected with the intermediate ornamental panel or coupling member 2. While for illustrative purposes there is shown in the drawing a very simple form of radiator shell of substantially inverted U shape, opened at the bottom, it is to be understood that the lower end of these side elements I may be interconnected by a transverse portion at the bottom or they may be initially formed with inwardly extending arms which may be united directly one to the other or interconnected by an intermediate coupling portion analogous to the interposed ornamental sections 2. Being mere duplication such bottom connection has not been shown.

Preparatory to the forming operation the sheet metal blank is initially bent into curvilinear form as at the point 3 and again bent reversedly as at A to adapt it to the shape of the forming die. rI'his initial bending of the sheet metal blank provides work holding areas 5 and 6 located at the ends of the oblong sheet and similar Work holding areas located at the longitudinal margins thereof. 'Ihese areas to be gripped, particularly those in the region of maximum draw are engaged between coacting ribbed and grooved matching areas of the blank holder to prevent undue iiow of the metal from the edges of the blank into the central area as the drawing operation is effected. Not only are the side elements l substantially L shaped in their longitudinal aspect but the cross section of each of these shell elements is approximately L shaped. The formation of the reverse contours of the right and left side elements from a single sheet of material produces a channel shaped formation and insures a uniform draw of the metal, particularly at the region of maximum depth which occurs at the longitudinal bend of the side elements. Such formation of the two side members of the radiator shell having like but oppositely contoured shapes at the same time enables displacement of the like amounts of material in opposite directions and thus produces a uniform stretch of the metal and a balanced resistance pressure upon the die. When the pair of side elements have been conjointly formed as illustrated in Fig. 4 the holding areas 5, 6, '1, and 8 are trimmed therefrom and the formed structure is cut along a medial line thereby producing the two concave L shaped forms indicated at I5 and I6 in Fig. 6.

The edges Il of the parts I5 and I5 may then be shaped if desired to form a ledge I 8 along which the shell makes contact with the face of the radiator core when assembled therewith. The separated parts I5 and I6 are welded or otherwise terminally united with the intermediate ornamental panel or coupling section 2 to form the complete radiator shell. This intermediate coupling member is ordinarily provided with the usual filler opening 2I through which water may be introduced to the completed radiator.

While the simultaneous production of right and left side elements at a single operation greatly facilitates the manufacture and minimizes cost of production and has a further advantage of affording equalized or uniform draw and die resistance pressure, it is to be understood that the members I5 and I6 shown in Fig. 6 may be independently formed in separate dies and subsequently united with an intermediate ornamental panel or coupling section 2 in the relation illustrated in Figs. 1 and 2.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specic features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any ci' its forms or modifications within the legitimate and valid scope of the appended claims.
